CSR is $450 (so $100 cheaper than AMEX Plat), comes with SPG Gold, which means you get Marriott Gold, $100 GE credit, $300 travel credit, Priority Pass. So in the years you don't use the GE credit, the card is still only $150 annual fee after the $300 travel expense credit. Plus I think the Ultimate Rewards points go farther. But that's just me. I have the best of both worlds because I'm also an additional cardholder on a family member's AMEX Plat.
